Environmental conditions, with soil type and highyielding sorts are the most important factors for the most effective wheat production. In the 2008/2009, the same sort, with the same agrotehnics gave completely different results on different soil types. In the same year, Srpanjka had 11, 6 t ha-1 yield on chernozem, while it had 7, 2 t ha-1 on eutric brown soil. Grain yield analysis shown that Srpanjka sort exibits its own potential also at poorer soil types. That is why Srpanjka has been sown at poorer soil types, while other soil types are intended for Lucija sort.
